The **T110012** is a standard nomenclature often used in the electronics industry for specific **Crystal Oscillators**, primarily associated with manufacturers like *Fox Electronics* or *Transko*. It serves as a frequency control component in digital circuits. --- ### 1. Technical Specifications The following table outlines the typical electrical characteristics for a T110012 crystal oscillator: | Parameter | Specification (Typical) | | :--- | :--- | | **Frequency** | 1.000 MHz (Commonly) | | **Package Type** | DIP-14 (Full Size) or DIP-8 (Half Size) | | **Operating Voltage** | 5.0V DC (±10%) | | **Output Type** | TTL / HCMOS Compatible | | **Operating Temperature** | 0°C to +70°C | | **Frequency Stability** | ±100 ppm (Standard) | ### 2. Pin Configuration For the standard 14-pin DIP package used by the T110012, only four pins are typically functional: * **Pin 1:** NC (No Connection) or Tri-state Control. * **Pin 7:** GND (Case Ground). * **Pin 8:** Output (The clock signal). * **Pin 14:** Vcc (+5V Power Supply). ### 3. Key Electronic Functions * **Clock Generation:** It generates a steady square wave pulse used to synchronize the operations of microprocessors and digital logic gates. * **Stability:** Unlike simple RC (Resistor-Capacitor) circuits, the T110012 uses a quartz crystal to maintain a highly stable frequency despite temperature fluctuations. * **Buffering:** Most parts in this series include internal circuitry to buffer the output, allowing it to drive multiple TTL loads without frequency degradation. ### 4. Common Applications 1. **Legacy Computing:** Often found in older 8-bit or 16-bit computer systems for bus timing. 2. **Industrial Controllers:** Used in PLCs or timing relays where a 1MHz reference is required. 3. **Baud Rate Generators:** Used in communications hardware to establish serial data rates. ---
